JONES WASTE BANK LEVELER 3 Sheets-Shea"V 5 Filed NOV. 29, 1948 Inventor Patented Apr. 14, 1 953 UNITED STATES PATENT OFFICEv WASTE BANK LEVELER Oliver L. Jones, La Crosse, Kans. Application November 29, 1948, Serial No. 62.440 1 claim. (C1. iss- 36) The present invention relates to waste bank leveler and it consists in the combinations, constructions and arrangements of parts herein described and claimed.

It is an object of the present invention to provide a waste bank leveler which is ad-apted to be mounted upon the platform of a truck whereby the same may be supported from place to place.

Another object of the invention is the provision of a waste bank leveler having a pair of coasting endless conveyor-type scraping mechanisms.

Another object of the invention is the provision of novel means for positioning the scraping mechanisms.

A further object of the invention is the provision of novel means for the transfer of power to the scraping mechanisms from a motor forming a part of the invention.

Other and further objects of the invention will become apparent from a reading of the following specification taken in conjunction with the drawings, in which:

Figure 1 is a side elevational view of an embodiment of the invention,

Figure 2 is a sectional view taken along line 2-2 of Figure 1,

Figure 3 is a fragmentary elevational View of a scraping mechanism forming a part of the invention,

Figure 4 is a plan view of Figure 3, and

Figure 5 is a perspective view of a scraper bucket forming a part of the invention.

Generally there is provided a waste bank leveling mechanism which is mounted upon the platform of a conventional truck and which consists essentially of a motor bolted to the platform, a plurality of masts and a pair of downwardly and outwardly disposed endless conveyor-type scraping mechanisms comprising chains to which are affixed a plurality of angularly disposed scraper buckets. Power is supplied to each of the scraper assemblies from the motor through shafts provided with universal joints and telescoping sections. The angle of each of the scraper assemblies may be changed through an arrangement of cable connections thereto which cables are given motive power from a motor mounted upon the platform.

Referring more particularly to the drawings, there is shown therein a conventional truck Ill having a platform to which is affixed an outwardly extending base member I2. Upon the base member there is permanently mounted, by

2 vided with a rearwardly extending shaft I5 having a bevel gear I6 at its outer end.

The gear I6 is enmeshed with a pair of bevel gears I1 each affixed to a transversely extending shaft I8 journaled, as indicated at I9, in the upper end of an upright member 20 affixed at either side of the base I2.

A mamma-st is provided and consists ofy a pair of legs 2| having feet 22 bolted adjacent either side of the case I2. The legs 2| converge at their upper ends and have mounted therebetween a pulley 23.

Between the legs 2| there is provided a pair of converging frame members 24 having mounted therebetween at their upper ends a revoluble spool 25 having an outwardly extending shaft 2liv to which a sprocket 21 is aixed and which sprocket is interconnected by means of a chain 28 to a sprocket 29 aixed to a transversely extending shaft 30 which is moved by the motor I4 and which is provided at its outer ends with spools 3|.

The spool 25 has afxed thereto and wound thereon a cable 32 which is trained over the pulley 23 and which has its outer end attached to a beam 33 to the opposite sides of which is hinged, as indicated at 34, a pair of downwardly and outwardly extending frames 35, each provided with an offset portion 35a.

Adjacent each of the sides of the base member I2 is axed a sub-mast 36 having a pulley 31 revolubly mounted at its upper end. Each of the spools 3| has axed thereto and wound thereon a cable 38 which extends upwardly and over its respective pulley 31 and thence downwardly to a yoke 39 which is pivotally connected to its respective frame 35, as indicated at 40.

The outer ends of the shafts I8 are each provided with a universal joint 4| which connects with a hollow shaft 42 in which, in each case is telescopically keyed a shaft 43 which is, in turn, provided with a universal joint 44 which connects with a shaft 45 extending through a journal 46 carried by a bracket 41 afxed adjacent the outer end of the frame 35.

The shaft 45 is provided with a worm gear 48 which is enmeshed with a worm Wheel 49 afxed to a shaft 50 which extends transversely of the frame 35.

The shaft 50 has mounted thereon a pair of sprockets 5| which are interconnected by means of chains 52 with like sprockets 53 aillxed -to a shaft 54 revolubly mounted in the upper and inner end of the frame 35. Each shaft 54 extends beyond its respective offset portion 35a and has mounted at its outer end a circular cutting means of brackets I3, a motor I4 which is pro- 55 disc 54a.

Vspaced at a maximum distance from yeach other on the chain 52.

In operation, it will be seen that the truck I may be driven in conventional manner to proximity to a waste bank 60 to be levelled and then backed into position, after which the motor 1.4 is

started and the truck moved backwardly until the buckets 55 come into contact'wi-th the vbank 6i). The scariers 59 will tend to loosen the earth composing the bank andthe buckets will thereupon remove the same 1as well as any material already in a loose condition.

It will be noted that the pull upon the buckets is exerted in a downward direction and that, hence, there is no tendency for the .endless chains 52 to buckle during the working of the apparatus. It will also be apparent that the outer ends oi the endless chains assemblies may be raised and lowered through the motor I4 operating through the shafts 3D, drums 3|, Acables 38 and yokes 3.9, suitable controls .being .provided for such apparatus. Again, the vbeam 35may be raised and lowered through the .cable 32'and drum 25 .shaft 26, chain 28 and motor I4 whereby the upper ends of Ithe frames 35 may be raised and lowered. Thus, as the bank 50 .is eaten away by the .operation of the apparatus forming this invention, the truck i0 may be moved from time to time to again bring the .same into contact therewith vand the working angles ofthe frames 35 may be changed at the will of the `operator.

While but one form of the invention has been shown and described herein, it will be readily apparent to those skilled in the art that many minor modications thereof may be made without departing from the spirit of the invention or the scope of the appended claim.

What is claimed is:

A scraper assembly comprising a frame, a pair of spaced parallel endless chains mounted for conventional movement in said frame, and a plurality of spaced scraper buckets transversely and angularly Vinterconnecting said chains, said buckets each comprising an elongated body of `,arcuate cross section, end Walls for said body extending parallel and yadjacent to said chains, an ear formed at the rear end of each of said end rwalls and connected to the adjacent chain, and a link interconnecting the forward end of each end Wall to the adjacent chain.
